IMPROVEMENT iN OILERS FOR LOOSE PULTLEYS.

Specification forming part of Letters Patent No. 124,333, dated March 5, 1572.

To all whom fit may concern:

Beit known that I, EDWARD L. GONKEY, ot' Boston, in the county ot' Sult'olk and State ot'AlVIassachusett-s, have invented a new and useful Improvement in Oilers for Loose Pulleys; and I do herebydeclare the following to be a full, clear, and exact description thereof sufticient to enable those skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawing making part of this specification.

This oiler consists of a cup or vessel, suitable for containing the lubricating-oil employed, that is constructed with a passage leading to the journal or shaft on which the loose pulley turns, and is provided with a movable head or piston in such a manner that the revolution of the pulley, through its centrifugal action on the said head or piston, Will force the oil through said passage to the jour.- nal. In addition to the above, the invention consists ot' a regula-tor in said oil-j iassage for regulating the supply ot' oil to the journal.

In the accompanying plate of drawing my improvements in Oilers for loose pulleys are illustrated, the ligure being a central vertical section ot an oiler constructed according thereto, and as applied to the hub of a loose pulley-Wheel. I

A in the drawing represents the cup or receptacle ofthe oil for the oiler. This cup is provided With a cap or head, B, adapted to be screwed on and ott' for supplying the cup with oil, and is also provided with a plug, C, for being screwed into the hub of the pulley- Wheel; a a, tubular passage, arranged in the present instance in the center of the cup, and extending from the bearing or journal ot' pulley nearly to the detachable cap or head B, forming a communication for the oil between the interior of cup A and the journal or bearing, as is obvious. D is a head or piston, arranged Within the cup A so as to move therein from end to end thereof, its periphery being provided with leather or other suitable packing to form a close joint. 'This head moves over the central oil-tube a.

An oiler constructed as above described, with oil in the space between the piston or head D and the movable cap to the cup, Will by the revolution of the pulley throw the piston D by centrifugal force outward from the hub in direct proportion to the speed of the pulley, forcing, as is obvious, the oil in the cup through the passage a to the bearing or journal.`

b, a screw located in cap B to cup A, and

in position when screwed in suciently to enter the open end of oil-passage ce, and thereby to open or close the same more or less' to the iiow otl oil through it to the journal of pulley-wheel, according' as may be found necessary to produce the proper lubrication ot' the part-s 5 c, air-holes in each end ot' the bottom of oil-cup A for the admission of air to the chamber of oil-cup back of the movable head or piston to overcome the vacuum made by the movement ot' the piston through the revolution ot' the pulley, as described. Y The oil-cup may be made with or Without a removable cap,-]5; but it is most convenient for use when so constructed, as it enables both the piston to be inserted or removed at pleasure and the cup to be charged With oil. The oil-passage may be at one side in lieu of the center, and if desired more than one passage may be arranged, it being only necessary that they should communicate with oil-cup and bearing or journal for loose pulley, substantially as described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An oiler for loose pulleys, Ste., having its oil-receptacle provided with a passage leading to the journal, a bearing ot' the pulley, and a head or piston, constructed and arranged together substantially as and for the purpose described.

2. In combination with the above, the regulator b or its equivalents to oil-passage, substantially as described, for the purpose specitied.'

3. The air-holes c, substantially as and ifor the purpose described.

The above speeilication of my invention signed by me this lst day of May, A. D. 1871.
